They look shinySo what is the benefit of those air boxes???. They are ok until you put the filter in then there is not enough room for it to all work correctly.

They do look good... hahaha.
Would there really be much benefit in getting an airbox like Oldmav suggested before for my setup, or is it more for the boys running bigger numbers?
Yes. The less restriction in your intake system the easier your turbo can work. Most people when they go to one of options suggested need to reset their boost as it generally increases with the less restrictive setup.Originally Posted by Winnie
Air filters are overrated!! Lol
I will try and explain this a little. I have already pointed out some of the things that are issues with a ZD box but don't get confused with my comments. I am somewhat a idealist so I always chase the 1% improvements. Its just that the ZD type air box design is very restrictive even for the ZD engine. Its not just the air box either the STD tubing from air box to turbo is terrible even the std snorkel tubing through the GU guard is terrible, So very simply the turbo tubing is a 1%er the guard tubing is a 1% er as you can see these 1% improvements all add up so there is good driveability improvements here not Kilowatts but torque rise and how quick that torque curve rises due to the turbos ability to spool faster and the turbo shaft speed or revs can stay more constant. This stuff you can feel in the seat of your pants even though it only improves KW marginally, torque changes is the stuff you feel and makes your rig nicer to drive due to flexibility or in this case engine response.
So Winnie there is considerable improvements by having a free flowing induction system it allows the full potential of your engine to be realised. But even for your patrol doctor there are improvements to be had by a simple element change. I will post a comment from another forum which a member took on my pointed suggestions to see what would happen.
Quote follows. using a patrol doctor Air Box.. He is also a member of this forum..
"well, thought I would have a play around with different filters in the ute...
went from a Ryco A1412 to a Ryco A1504 (which is the filter that suits the 3L diesel rodeo's) and happily got some positive results.
my MAX EGT's have reduced from 550degC to 500degC.
my max boost has increased from 15psi to 17psi.
from eye, rpm and boost response seems to be a touch more responsive.
from the seat of the pants, seems a touch better then previously.
happy with that result."
So you see a simple element change has a considerable effect to driveability which should suggest to you how fail that air box really is without even considering filtration issues due to air speeds. Imagine if he had a FATZ or a Millweld or a simular panel big HP airbox with ideal induction tubing. I call these improvement things 1%ers because they increase driveability and response which is the stuff we feel and want for our rigs not outright bragging rights that big KW numbers have. Even though to get higher torque which is the stuff we feel we need KW to maintain this power, hence why I have big numbers. Big KW numbers are easy to get, more fuel more air pumped = big numbers, I broke the 200rwkw value April 1990 24 years ago but you couldn't drive the bloody thing on the road it was madness to drive. Its taken 24 years of stuffing about to get real improvements and I am still playing.
I've used K&N filters in most of my 4WD's and love them , But i haven't put one in the Patrol because the other K&N's I have used have to be sprayed with oil after cleaning and didn't want to cover the MAF sensor in oil !
Yeh, and fark they are spencive for a 4.5L !
I'll give ya a $100 for your rear bar if that helps lol
If ya not using it buy a prius .....
Haha, that wont even cover the cost of the lights Stevo !I'll give ya a $100 for your rear bar if that helps lol
It's all a bit of philosophy and commercialism I reckon.
Back in the early, mid 20th.C. you serviced your wheels and an air filter had a foam element which you cleaned with a kero bath, dried , reoiled and but back. Lasted damn near forever and worked a treat.
21st.C. and the vast majority don't know where the bonnet release is let alone what's in there. ALSO, MOST IMPORTANTLY, the manufacturers want you to buy new every time, all the time. Answer?. Replaceable paper air filters. Dead quick, dead easy, dead profitable. Don't work as well but shoot, there's money in a replacement engine in quicker time anyway.
As always, it's a matter of time, knowledge, effort and convenience. Bit like women really. The late models look real good but expensive whilst the old one's really, really reliable and you know what you're doing and where you're going.
Cheers
Col.
